Employing the laws of BODMAS, ((25/5) x 4) - (15 x 8) = -100
25 times 6 times 25 minus 8 plus 12 divided by 5 = 3,744.4
6 divided by 3 times 25 minus 25 = [(6/3)*25] - 25 using the rules which define the order of operations (BIDMAS/BODMAS or a variant). = [2*25] - 25 = 50 - 25 = 25
3+25-25+3-4=2
15/25 divided by 16/25= 15/25 times 25/16= 375/400= 15/16
15 - 25 = -10
Minus 25 (5x5=25 if there is one minus then the answer is minus).
-25 - 10 = -35
25 minus 15 is 10.

-10 - 15 = -25
